ERNEST BRASCH, OF NEZPERCE, IDAHO 'ATTACHMENT FOE HARVES'IEBSApplication filed January 1 1, 1928. Serial No; 2443,0735" The presentinvention relates to combined harvesters and has particular relation tomeans for keeping the harvester body in a level position, so that whentravelling over rough or hilly ground, the body of the machine will beautomatically level and sheeperation of the mechanism facilitated.

Another object of the invention is to provide novel means foraccomplishing the above, which is simple and efficient in operation andwhich may be easily and quickly incorporated as part of the levelingmechanism of a harvesting machine. V

With the above and other obJects in view,

' the invention further includesthe following novel features and detailsof construction to be hereinafter more fully described, illustrated inthe accompanying drawing and pointed out in the appended claims.

In the drawing:

Figure 1 is a rear view of a separator with my improved constructionassociated therewith,

Figure 2 is a fragmentary top plan view thereof,

' Figure 3 is a fragmentary front elevation, thereof,

Figure 4 is a vertical section taken sub stantially on the line 4-4 ofFigure 2,

Figure 5 isa. detail sectional view showing the gearing,

Figure 6 is an end elevation thereof, and

Figure 7 is a horizontal sectional vlew through the attachment.

seen that the numeral 5 denotes a separator having a shaft 6 projectingtherefrom and operated by the drum thereof and journaled in a gearcasing 7. A gear 8 is fixed on the shaft 6 within the casing 7 andmeshes with a pinion 9 on a shaft 10 journaled in the casing andextending therefrom to a gear casing 11. A pinion 12 is on the other endof the shaft 10. The housing 11 has a shaft 13 journaled therethroughand the exterior end thereof is provided with a beveled pinion 14. Apair of gears 15 are rigid on the shaft 13 within the casing 11 and meshwith pinions 16 on a shaft 17 journaled in the casing 11.

Referring to the drawing in detail it will be Clutch disks 18 and 19 aremounted on the shaft 12. Gears 2O and'21 are loose on the shaft 7 andeach comprises a beveled gear por tion a and a clutch face portion 6.The gear 20 further includes a crown gear portion'o. A head 22 hasjournaled thereon a pinion 24 meshing with the beveledge'ar portion a ofgears 20 and 21. The pinion 12 meshes with the crown gear portion cs0that the gears 20 and 21 and the pinion 24 are in constant rotation. Apendulum shank 26 is fulcrumed in.-*

termediate its ends'as at 27 and has a'heavyweight on the'lowerextremity thereof as at 29. A screw threaded bar- 30 is pivotally en- 4gaged as at 31 on the frame35 andjhas a mooring 36 through which-itextends and a second mooring 37 in whichthe upper end there of isdisposed. Tie rods38 connect the moorings 36 and 37. Cylindrical canvascovers 39 and 40 extend respectively toward each other I w from moorings37 and 36 and are connected together at their innerends by suitablemeans 41. A nut member 42 is threaded on the bar 30 and has a beveledgear portion 43 meshing with'pinion 14 which is journaled through abracket 44 on the arm 45.. This bracket 44 has extension 46 withinwardly directed pins 47 extending into a grooved collar 48 formedonthe nut member 42.

Now if the combined harvester were going along a hillside that slantedto the. right, the combine is slanting in the same direction within theincentive or pendulum lever 26 to swing away from the combines separatorin an "attempt to keep itself adjusted parallel I with alined forcegravity. Thisactionfbrings the whirling clutch'20 over in contact with'clutch plate 18 thus setting the'system of gears in motion causing thenut member 42 in turning to climb the smooth bar 30 and since the jseparator fastens to it to arm 45 it is carried out of the tiltto a'position of leveL} When this point is reached, the ball and pendulumlever keeping itself adjustedparallel with the force of gravity, takesthe whirling clutch V out of contact. If the combine should happen tolead to the left just the opposite would occur as will be apparentbyconsidering the eflg gement of clutch 21 with clutch 19 as the 9 gearswouldthus be revolved a reverse diing them into engagement with theclutch rection and the nut member would move down I claim as new is:

on the screw bar.

It is thought that the construction, operation and advantages of theinvention will now be quite apparent to those skilled in this artwithouta more detailed description thereof. r

The present embodiment of the invention has been disclosed indetailmerely by way ,of example since in actual practice it attains thefeatures of its advantage enumerated as desirable in the statement ofthe invention and the above description. 'It willb'e'appa'r'ent thatchanges in the details of construction, and in. the icombination and.arrangement. of parts may be resorted to without departing from thespirit or scope of the invention as hereinafter claimedior sacrificingany of its advantages; I 4
